How to Hire Java Developers

Java has been at the forefront of tech development for a long time. In 2017, it is still incredibly popular amongst a variety of groups — many corporate applications require its stability and reliability. Start-ups also appear to be eager to hire Java developers, as their products are often interesting, and can provide a change from typical banking or calculation-heavy projects. Even Indeed — “the world’s #1 job site” — analyzes Java postings to identify the world’s top tech cities.

To put the sheer scope of Java into perspective, here are some statistics from Java Sample Approach:

97% of enterprise desktops run Java

89% of computers in the U.S. run Java

There are 9 million Java developers across the globe

Java is the number 1 choice for developers, as well as the number 1 development platform.

3 billion mobile devices run Java

100% of Blu-Ray Players utilize Java

5 Billion Java cards are being used today

125 million televisions run Java

The top 5 original equipment manufacturers ship Java ME

With Java being such a vast language, it makes sense that many developers learn it. But, this raises the question:

Are Java Developers in Demand?

According to data from Gooroo, programmers with skills in Java development are needed more than any other specialized developer in the U.S..

This is in line with a recent Stack Overflow report, that shows how the demand for Java developers outpaces supply.

What technologies are in the highest demand?

This data resonates even more when we look at the language’s popularity.

Programming languages popularity

These statistics from IEEE Spectrum are rather useful, as they take into account not only the popularity amongst employees, but also job trends. When they are combined with this next graph from Indeed, the sheer popularity and demand of Java really comes into focus. Over the past two years, it has continued to grow.

Job seekers interest in Java development

Consistent updates have kept Java beyond normal relevancy, and it rarely loses ground against other languages. Due to it being an elite technology with a high learning curve, this is unlikely to change anytime soon. Companies will continue to need Java for the foreseeable future, as it is ingrained within both needed projects, existing applications, and the very developers themselves. Upcoming technology can also be expected to require it — due to the high levels of time and commitment required to become a Java programmer, they are often the people creating new developments in the tech world.

What is the Average Java Developer Salary?

Java’s flexibility isn’t the only reason developers like it – it also pays very well. Take the U.S. for example — being the country that generates the highest demand for developers, it also has the highest wages.

Indeed suggests that the Java developer average salary there is around $102,064, with Junior developers earning less, at around $70,389 on average. A senior Java developer can expect to earn about $116,293, but one key factor to remember is location. Average wages increase if we look at the country’s biggest tech cities: according to more data from Indeed, San Francisco, New York and Los Angeles all have wages well above the average.

Average Java Developer Salaries in the Biggest U.S. Tech Cities

San Francisco

$133,648

New York

Even Houston — which is around $18,000 lower than the national U.S. average — is higher than typical Java programmers worldwide. To determine these worldwide statistics, we used PayScale.

As we can see, Switzerland tops this chart with a wage of $83,299 — reinforcing its position as one of the highest paying countries in software development. On the other end, you will find Java developers in Finland, the Netherlands and France all earning around $44,000.

The substantial demand for Java programmers certainly goes some way in explaining these high wages — especially in locations where the local Java talent pool is limited. The cost of living is also a substantial factor, which should not be forgotten. These reasons are why many companies consider offshore locations Java development needs. Ukraine is a beneficial outsourcing location because of both the lower cost of living, and the huge talent pool; a pool which yields a higher chance of a recruiter finding talent with the correct Java developer requirements.

Java Developer Interview Questions

Before you think of how to interview Java developers, you need to remember the scope of the language. It’s important to pinpoint your exact project needs prior to searching for talent. There is a high demand for them — but in particular, middle and senior ones. These experts will seek specificity in your brief, and are the people you will be wanting for your project. Make sure your job listings and recruitment methods appeal to these programmers by providing full, relevant, and interesting information, in order to attract them to your goals.

Regardless of the developer’s resume, you should begin this process with some typical questions that can be applied to Java as a whole. Here are some good Java developer basic interview questions to ask a middle-level programmer:

What’s the difference between a HashMap and a TreeMap? How do they work? How long do they take to access objects?

What standard Java tools have you used on previous projects, in order to implement a thread pool?

Explain the difference between ServletContext and ServletConfig.

What’s a RequestDispatcher?

Don’t be afraid to be very specific, however. It’s likely your project will require the use of other technologies: frameworks such as Hibernate and Spring are commonly used with Java, for example — so if your project requires them, be sure to test the knowledge of the candidate in the interview process:

Explain the DI and IoC patterns.

What types of DI are there? Give examples.

What is AOP?

Explain how the BeanFactory works in Spring.

What’s lazy loading, and what are the best ways to achieve it in Hibernate?

What object loading strategies are there in Hibernate?

What types of cache are used in Hibernate?

How do you solve N+1 problems in Hibernate?

What does the life cycle of a Spring bean look like?

What’s the difference between the startComponent; ?>, @Repository, and @Service annotations in Spring?

What types of Spring bean scopes do you know?

What are the different types of autowiring in Spring?

These questions will help you analyze your candidates; testing their knowledge, history, and ability is of course useful, but you must ensure several other factors are met, especially if considering offshore Java developers. The potential developer must fit into your company philosophy — it’s definitely true that relations personnel and retention can help the candidates once chosen, but a useful direction is to hire people you think would share your aims, and fit into your company environment. What a Java developer should know, should not be the sole factor in recruitment.
